A light source ( 100 ) provided herein generally includes a substrate ( 110 ), a cathode ( 120 ), an isolating layer ( 122 ), a light-permeable anode ( 152 ), and at least one fluorescent layer ( 154 ). The substrate has a surface, and the cathode, with at least one solid electron emitter formed thereon, is located on the surface of the substrate. The isolating layer is formed on the cathode. The light-permeable anode faces the field emitters and is spaced from the cathode to form a vacuum chamber. The at least one fluorescent layer is formed on the anode. Such a light source can then be incorporated, e.g., into a backlight module ( 300 ) for an LCD device.
